Israeli strikes killed at least 72 people across Gaza overnight and into Saturday, health workers said, as ceasefire prospects were said to be improving after 21 months of war.

Israeli air strikes have killed 14 Palestinians in the Gaza Strip, including 10 as they sought food in the embattled enclave, hospital officials told reporters.

Three children and their parents were killed in an Israeli strike on a tent camp in Muwasi near the southern city of Khan Younis. They were struck while sleeping, relatives said.
